Answer:
The spectator ions is: and
Explanation:
The equation of reaction between H₂ SO₄ and KOH is:
Rewriting this equation as ionic;
Spectators ions are ions present on both sides of the ionic equation by the same quantity but do not take part in the net reaction.
Answer: b} The exact time when an individual atom will decay can be accurately predicted.
c} After each half-life, the amount of radioactive material is reduced by half.
Explanation:
All radioactive decay follows first order kinetics.
Rate law expression for first order kinetics is given by:
where,
k = rate constant
t = time taken for decay process
a = initial amount of the reactant
a - x = amount left after decay process
Expression for calculating half life, which is the time taken by the half of the reactants to decompose is:
